The average distance between the two adjacent base pairs is 0.34nm (0.34 x 10 -9 m or 3.4 A). The number of base pairs in Escherichia coli is 4.6 x 10 6. The total length of its DNA is 1.36 mm.
Crafting the ladders. 1  1. Place the 7 sticks in the crafting grid. Arrange as follows: Place 3 wooden sticks down the left column slots of the grid. 2  2. Craft the ladder. You'll get 3 ladders. 3  3. Shift click or drag to your inventory.
Take the height you are trying to reach. Add three feet (so that you have something to hold onto at the top once you get up there). Add an extra foot for every four feet of height (to account for your angle). In your example 25 + 3 + 6 = 34. The formula for this is: (h Ã· 4) = (a). h + 3 + a = l (where h = the height of your house, a = the amount you should allow for your angle, l = the length of ladder you need).
